Try this code.I have tested, it is working for me in swift3.0.

        let myDate = "2017-08-12 11:30:00"
        let localDateFormat = DateFormatter()
        localDateFormat.dateFormat = "YYYY-mm-dd hh:mm:ss"
        let localDate = myDate)
        localDateFormat.dateFormat = "EEE, dd MMM yyyy hh:mm a"
        let myNewDate = localDateFormat.string(from: localDate!)
        //GMT Date
        let gmtDateFormat = DateFormatter()
        gmtDateFormat.dateFormat = "HH:mm a"
        gmtDateFormat.timeZone = NSTimeZone(abbreviation: "GMT")! as TimeZone
        let gmtDateString = gmtDateFormater.string(from: localDate!)
